Dynamic demographic models and parameter identification: Simulations based on statistical data
(Institute of Electrical and Electronics Engineers Inc., 2014)This paper is concerned with dynamical population models obtained from short and long-term changes in size and age composition due to demographic processes such as births, deaths, migration, etc. Both deterministic and ...

Estimation and identification of time-varying long-term fading wireless channels with application to power control
(Institute of Electrical and Electronics Engineers Inc., 2007)This paper is concerned with modeling of time-varying wireless fading channels, parameter estimation, identification, and optimal power control from received signal measurements. Wireless channels are represented by ...

Exact filters for Newton-Raphson parameter estimation algorithms for continuous-time partially observed stochastic systems
(IEEE, 1999)This paper presents explicit finite-dimensional filters for implementing Newton-Raphson (NR) parameter estimation algorithms. The models which exhibit nonlinear parameter dependence are stochastic, continuous-time and ...

First measurements of inclusive W and Z cross sections from run II of the fermilab tevatron collider
(2005)We report the first measurements of inclusive W and Z cross sections times leptonic branching ratios for pp collisions at √s = 1.96 TeV, based on their decays to electrons and muons. The data correspond to an integrated ...

Global optimization for motion estimation with applications to ultrasound videos of carotid artery plaques
(2010)Motion estimation from digital video is an ill-posed problem that requires a regularization approach. Regularization introduces a smoothness constraint that can reduce the resolution of the velocity estimates. The problem ...

Hierarchical decentralized fusion from correlated sensor measurements
(2005)In this paper we consider hierarchical decentralized fusion of possibly correlated noisy measurements of a random variable. Our goal is to obtain initial estimates in a decentralized fashion (based on disjoint groupings ...

Higher-order accurate polyspectral estimation with flat-top lag-windows
(2009)Improved performance in higher-order spectral density estimation is achieved using a general class of infinite-order kernels. These estimates are asymptotically less biased but with the same order of variance as compared ...

Identification of hysteretic systems using the differential evolution algorithm
(2001)A widely used model in the field of hysteretic or memory-dependent vibrations is that of Bouc and Wen. Different parameter values extend its use to various areas of mechanical vibrations. As a consequence an identification ...

Implicit-explicit BDF methods for the Kuramoto-Sivashinsky equation
(2004)We consider the periodic initial value problem for the Kuramoto-Sivashinsky (KS) equation. We approximate the solution by discretizing in time by implicit-explicit BDF schemes and in space by a pseudo-spectral method. We ...

An indirect adaptive control design with anti-windup compensation: Stability analysis
(2007)We combine an adaptive law with a control design including a Linear Quadratic (LQ) controller and a Linear Matrix Inequality (LMI) based anti-windup compensator using the certainty equivalence principle for asymptotically ...

Inference for Some Multivariate ARCH and GARCH Models
(2003)Multivariate time-varying volatility models have attracted a lot of attention in modern finance theory. We provide an empirical study of some multivariate ARCH and GARCH models that already exist in the literature and have ...

Least-cost transition firing sequence estimation in labeled petri nets
(2006)This paper develops a recursive algorithm for estimating the least-cost transition firing sequence(s) based on the observation of a sequence of labels produced by transition activity in a given labeled Petri net. Each ...

Measurement of partial widths and search for direct CP violation in D 0 meson decays to K-K+ and π -π+
(2005)We present a measurement of relative partial widths and decay rate CP asymmetries in K- K+ and π-π+ decays of D0 mesons produced in pp̄ collisions at,√s = 1.96 TeV. We use a sample of 2 × 105 D*+ →D0π+ (and charge conjugate) ...

Model Reference Adaptive Control for Plants with Unknown Relative Degree
(1993)One of the basic assumptions in stable model reference adaptive control (MRAC) that the relative degree n002A of the modeled part of the plant is known exactly and matches that of the reference model is relaxed by the ...

Modeling and control design for a computer-controlled brake system
(1997)The brake subsystem is one of the most significant parts of a vehicle with respect to safety. A computer-controlled brake system has the capability of acting faster than the human driver during emergencies, and therefore ...

Modeling and inference for multi-state systems
(2018)In this work we are focused on multi-state systems modeled by means of a special type of semi-Markov processes. The sojourn times are seen to be independent not necessarily identically distributed random variables and ...
